A system for generating hydrogen gas utilizes a volume exchange housing for the storage of a fuel material that reacts to generate hydrogen gas and a hydrogen separation chamber. The system includes a gas permeable membrane or membranes that allow hydrogen gas to pass through the membrane while preventing aqueous solutions from passing therethrough. The system is orientation independent. A throttle valve is also used to self regulate the reaction generating the hydrogen gas.
